Efficacy of a Liquid Live Micro-organisms System, to Reduce Sediments and Improve Water Quality and Koi Carp Production in Hatchery Ponds

Turbidity and sediments in hatchery ponds can adversely impact water quality and fish production. To reduce turbidity, hatchery managers use chemical coagulants, chopped hay, or cottonseed meal. However, the turbidity-causing substances removed from the water column sink to pond bottoms as sediments which, when the pond is drained, can pollute receiving water bodies. For hatcheries to operate within effluent discharge limits, total suspended solids (TSS), total settleable solids, total ammonia nitrogen, pH and carbonaceous biochemical oxygen demand (CBOD) must be effectively managed.
